And prolific in the doorway and analysis often -- hopefully within a couple of years we heard the commentary and get to a we've. Kofi of affluent. -- who -- reflect on that. Got the HBO -- you've got the book out. In the book I was struck by when a lot -- that you -- you said I was -- declined to the top of the sky and tumbled down.
